    Notes: Summary The three-dimensional ultrastructure of glomerular basement membrane (GBM) and mesangial matrix (MM) at an early stage of streptozotocin (STZ)-induced diabetes mellitus in rats was examined by the quick-freezing and deep-etching method. In diabetic rats, the GBM inner layer was diffusely enlarged and the meshwork structure not only in the GBM middle layer but also in the MM became markedly irregular due to the rupture of fine fibrils. This irregularity and enlargement of the mesh pores in diabetic rats developed during the experimental period and was significantly different from results in control rats. Insulin treatment from 1 week after STZ injection had significant effects in preventing the ultrastructural changes in the GBM and MM. It is suggested that early insulin treatment has significant effects in preventing size barrier disturbance of GBM and MM in STZ-induced diabetes.

    Description / Table of Contents: Zusammenfassung Bei der Bestimmung des globalen Optimums werden in der Vektoroptimierung intervallanalytische Methoden angewendet. Hier diskutieren wir Optimierungsprobleme, bei denen mehrere Zielfunktionen in Konfliktsituationen optimiert werden müssen.
    Notes: Abstract Interval Analysis methods have been applied for obtaining the global optimum of the multimodal multivariable functions. We discuss here the multicriterion optimization problem, where several objective functions must be optimized in conflicting situations.
